2-Bromo-5-methylpyridine is a vital halogenated methylpyridine heterocyclic intermediate. It is widely used in Suzuki coupling, Buchwald amination and nucleophilic substitution reactions in organic synthesis. It acts as a key building block for the synthesis of pharmaceutical APIs, anti-cancer drugs, anti-inflammatory agents and central nervous system targeted compounds. The bromine site is easy for structural derivation and molecular modification, while methyl group improves molecular stability and lipophilicity. It is also commonly used in agrochemical intermediate synthesis, fine chemical custom synthesis, medicinal chemistry research and new functional organic material skeleton construction.

Causes skin irritation and serious eye irritation. Inhalation of vapor or dust may trigger respiratory discomfort and cough. Avoid inhalation, direct skin and eye contact. Operate in fume hood with chemical resistant gloves, safety goggles and dust respirator. Store tightly sealed in cool, dry, dark and ventilated place, keep away from heat, fire source and strong oxidants. In case of contact, rinse skin and eyes with plenty of running water for several minutes. Waste shall be disposed as hazardous chemical waste, forbidden to discharge directly into sewer and water environment.
